Beckett Boiler Troubleshooting: A Guide for Homeowners

Beckett boilers are oil-fired heating systems that provide hot water or steam for your home. They are efficient, reliable, and easy to maintain, but like any appliance, they can sometimes have problems. If your beckett boiler is not working properly, you may need to troubleshoot it to find the cause and fix it. Here are some common issues and solutions for beckett boiler troubleshooting.

No Heat or Hot Water

If your beckett boiler is not producing any heat or hot water, there are several possible reasons. Some of them are:

  • No power: Check the power supply to the boiler and the primary control. Make sure the circuit breaker is not tripped and the fuse is not blown. If the power is on, check the voltage at the primary control input connections. It should be between 110 and 120 volts AC.
  • No oil: Check the oil level in the supply tank. Make sure all valves in the oil lines are open. If the tank is empty, refill it with the proper grade of heating oil.
  • No ignition: Check the burner for signs of ignition. If the burner does not light, there may be a problem with the electrodes, the transformer, the nozzle, the oil pump, or the primary control. You may need to clean, adjust, or replace these components.
  • No circulation: Check the water pressure and temperature in the boiler. If the pressure is too low, you may need to add water to the system. If the temperature is too high, you may need to lower the thermostat setting or bleed the air from the radiators. If the circulation pump is not working, you may need to replace it.

Burner Runs, Then Stops and Locks Out

If your beckett boiler burner runs for a while, then stops and locks out, there may be a problem with the flame detection or the safety controls. Some of the possible causes are:

  • Dirty or faulty flame sensor: The flame sensor is a device that detects the presence of a flame in the burner. If the sensor is dirty or defective, it may not sense the flame and cause the burner to shut down. You may need to clean or replace the flame sensor.
  • Faulty primary control: The primary control is a device that monitors and controls the operation of the burner. If the primary control is faulty, it may not send the correct signals to the burner and cause it to lock out. You may need to reset or replace the primary control.
  • Insufficient draft: The draft is the flow of air and flue gases through the boiler and the chimney. If the draft is too low, it may not provide enough oxygen for the combustion or remove the exhaust gases properly. This may cause the burner to produce smoke, soot, or carbon monoxide, and trigger the safety devices to shut it down. You may need to check and clean the flue pipe, the chimney, and the draft regulator.

Noise or Vibration from the Burner

If your beckett boiler burner makes a loud noise or vibrates excessively, there may be a problem with the combustion or the mechanical parts. Some of the possible causes are:

  • Improper air or oil adjustment: The air and oil adjustment is the process of setting the correct amount of air and oil for the burner to achieve the optimal combustion. If the air or oil adjustment is not correct, it may cause the burner to produce a whining, roaring, or rumbling noise. You may need to adjust the air shutter, the oil pressure, or the nozzle size.
  • Worn or loose parts: The burner consists of several moving parts, such as the motor, the fan, the pump, and the coupling. If these parts are worn or loose, they may cause the burner to vibrate or make a squeaking, grinding, or clanking noise. You may need to tighten or replace these parts.

Table of Common Issues and Solutions

Issue Possible Cause Solution
No heat or hot water No power Check the power supply and the voltage

No ignition Check the electrodes, the transformer, the nozzle, the oil pump, and the primary control
No circulation Check the water pressure and temperature, the thermostat, the radiators, and the pump
Burner runs, then stops and locks out Dirty or faulty flame sensor Clean or replace the flame sensor
Faulty primary control Reset or replace the primary control
Insufficient draft Check and clean the flue pipe, the chimney, and the draft regulator
Noise or vibration from the burner Improper air or oil adjustment Adjust the air shutter, the oil pressure, or the nozzle size
Worn or loose parts Tighten or replace the motor, the fan, the pump, and the coupling
